WebMar 31, 2024 · Another important input to estimating the rate of distributed seismicity is event magnitudes listed in earthquake catalogs. A substantial source of uncertainty in catalogs is the magnitude assigned to a given earthquake. Numerous different magnitude types exist, with each magnitude type computed in a different way. citizens national bank online bankingWebHowever, major earthquakes that have a magnitude of 7 or larger occur more than once per month around the world.
